A cheery fellow is a gladsome guy.

Torturesome

A whole day of this?

Wearisome

Another full-day workshop that nobody told me about? And it starts in five minutes?

Worrisome

The collapse of civilization is certainly worrisome.

3D Gears Math

SO here is the information for making 3D gears that all fit together. I used Sketchup for the design. All the gear convexities and concavities are 3-inch half-circles.

6-Spoke Gear

12-sided circle

Rotated 7.5 degrees

12-Spoke Gear

24-sided circle

Rotated 15 degrees

24-Spoke Gear

48-sided circle

Rotated 3.75 degrees

Rectangular 14-Spoke Gear

12- by 24-inch rectangle

Nettlesome

Something that is annoying is nettlesome. The nettle plant stings. It is, by definition, nettlesome. See also bothersome, troublesome. (P.S. Where’s Charles?!)

3D Gears

After having discussions with my math peeps, I decided to make gears. From scratch, in Sketchup. Many failures ensued. Thankfully, a Youtube video showed me the light (granted, I had to watch the video about 20 times).

Anyway, the gear ratio works (don’t ask me what that means), and different sizes of gears spin with each other. I even got fancy with irregular shapes (see the long gear) as well as gears with cut-outs (to save filament) and a gear with holes (to create abstract designs a la Spirograph).

Spinning Tree

This is a 3D printed tree that has movable branches.

I made it in Sketchup of simple geometric shapes, each rectangle just a wee bit smaller than the lower one.

The top part of the tree was actually a bit of challenge to create, as I had to create the triangle shape, but then make a partial hole through one side of it. There are three versions of it in the illustration above.

I exported each piece separately into Makerbot and then printed them one at a time.

Here are some more views of the tree.

Cuddlesome

Just like a big ol’ teddy bear!

Bothersome

A pest. A bother. An annoying person. See troublesome.
